Interpreting EEG requires understanding how the skull smears electrical fields as they propagate from the cortex. I made a browser-based simulator for my EEG class to visualize how dipole depth/orientation change the topomap.

Why Causal Knowledge Is Pragmatically Possible: Bridging Philosophical Skepticism and Scientific… When we observe the world, we note that events consistently follow one another. As David Hume famously argued in An Enquiry Concerning…

Great article by @kordinglab.bsky.social‬ on "why causal knowledge is pragmatically possible".

The best arguments for causation--& only one we need--is pragmatic. Here pragmatic isn't weak/subjective, but connected to actual goals, utility & outcomes in the world.

Multisensory flicker modulates widespread brain networks and reduces interictal epileptiform discharges - Nature Communications Repetitive audio-visual stimulation, or sensory flicker, can modulate oscillations in a non-invasive manner. Here the authors demonstrate the potential of flicker in individuals with epilepsy undergoi...

I recently purchased a standing desk, and it's been the best choice ever! My back is grateful :D

Hi everyone! I've joined BlueSky now. Although I'm not very active on these platforms (sorry, I don't have much time), I'll be reading your messages and sharing those that I find interesting! ;)
